Description
Summary:This paper presents a finite element investigation on the structural behavior of replaceable I-beam-to-CHS column joints with external diaphragm plates under cyclic loads. The finite element methodology was validated against complementary experimental results and satisfactory comparisons were observed between numerical and experimental results on the hysteretic curves, initial stiffness, bearing capacity, and energy dissipation. While validating the numerical models, two key parameters — preloading force and bolt hole sizes were identified which have significant effects on the structural performance. Based on the numerical and experimental results, recommendations on the design procedures were proposed. •Investigated integrated hysteretic behavior of the replaceable I-beam-to-CHS column joints through finite element analysis.•Illustrated the influence of preloading force and shape of bolt holes on the behavior of this joint•Provided design recommendation for this type of joint
